My all-time favorite is the bellman at the hotel who carries your bags from the lobby to your room. He shows you how to open the drapes, how to turn on the TV, and how to run the thermostat and stands there with his hand out, hemming and hawing, refusing to leave, clears his throat, shoves his hand out further, shifts his weight back and forth, mutters something. You have to pay him to leave.
Whenever possible I carry my own bags.
